A Review on Novel Techniques for Chalcopyrite Ore Processing

Chalcopyrite is the primary mineral which by alteration and successive enrich with copper produces the series, starting with chalcopyrite and going through bornites (Cu 5 FeS), covellite (CuS), chalcocite (Cu 2 S) and ending rarely as native copper (Brantley, 2003).

Why the Extraction of Copper from Chalcopyrite is so

Why the Extraction of Copper from Chalcopyrite is so

About 3/4 th of Copper (Cu) produced in the world has come from Chalcopyrite (CuFeS 2), but it is the lowest standard ore of Copper. The method used to extract copper from its ores depends on the nature of the ore. Sulphide ores such as chalcopyrite are converted to copper by a different method from silicate, carbonate or sulphate ores.
